Ma hope o ke kalai ʻanalapaʻau wela onā kalaiwa nuimahopeke kalaiwa anaka hana ʻana, ma hope koke o ke kāhea ʻia ʻana o ka mālama welahoʻopale ʻanalapaʻau wela. ʻO ke kumu ohoʻopale ʻanaʻO ka hoʻomaʻamaʻa wela o nā forgings nui ka mea nui i ka de-stress, recrystallize ka hoʻomaʻemaʻe palaoa a me ka dehydrogenation i ka manawa like.
1. Hoʻomaʻamaʻa Recrystallization Ma hope o kekahi mau hana recrystallization o nā forgings nui, hoʻomaʻemaʻe palaoa, hoʻomaikaʻi microstructure, hoʻomaikaʻi i ka hana.
2. Dehydrogen annealing e hoemi i ka hydrogen i loko o kake kalaiwa anas i ka palena hydrogen maʻiʻo ma lalo, a hana i kona mahele like, i mea e pale aku i ka pilikia o ke keʻokeʻo kiko, hydrogen embrittlement.

ʻOkoʻa ka coefficient solubility a me ka diffusion o ka hydrogen ma ka māhele 7 a me ka māhele A, ʻoi aku ka nui o ka solubility haʻahaʻa a me ka coefficient diffusion nui o ka hydrogen i loko o ka māhele A, e hoʻomau mau ana ka hydrogen i waho i ke kaʻina hana annealing. Hoʻohui pinepine ʻia ka annealing dehydrogenation me ka recrystallization. ʻO ka mahana o ka dehydrogen annealing maʻamau he 650 ℃. Ma hope o ka hoʻopili ʻana, pono e hoʻomaha mālie e like me ka hiki ke pale i ke kaumaha hou o loko. Hoʻokaʻawale ʻia ka hoʻoluʻu maʻamau i ʻelua mau ʻāpana: ma luna o 400 ℃, ma muli o ka plasticity maikaʻi o ke kila, ʻaʻole maʻalahi ke koʻikoʻi o loko, no laila hiki ke wikiwiki ka hoʻoilo; Ma lalo o 400 ℃, e lohi ka nui o ka hoʻoilo. No ka forgings me ka nui o nā mea hao a me nā koi o ka hana kiʻekiʻe, hoʻokahi a i ʻole ka nui o ka recrystallization mālama wela ma hope o ka forging, i mea e hoʻomaikaʻi ai i ke ʻano a me ka hana o nā forgings.
